PUNGHING MACHINE FOR STATISTICAL CARDS.

Application filed June 30, 1925, Serial No. 40,624, and in Germany July 3, 1924.

This invention, relates to a punching machine for statistical or filin cards of that kind in which all the punc es are first set and then all the holes are punched simultaneously. Two kinds of punching machines are at present known. In one of them the unches are singly and consecutively set y means of a keyboard with ten keys, by means of a setting mechanism to advaiicingstepby step like the carriage of "aptypewriter and connected to the keyboard. the second kind, slides are provided to the same number as that of the rows of punches, or a full keyboard. The slides id form, so to speak, a large keyboard wlth all the numbers thereon.

The first construction presents the dis advantage that the operator cannot observe the setting, so that errors are easily liable an to occur. In the second construction, the disadvantage is the large space occupiedhy the setting board, and the consequent chiticulty to observe at a glance what has been set, as well as the complication of setting tit by pulling the slides.

The disadvantages of both constructions are eliminated by my invention. This invention substantially consists in a limited size keyboard with all the numbers thereon,

to for instance of nine places, being mounted adjustably directly above the punch boxes which are stationary as in the known constructions, and moved by means of a separately arranged tabulator after a group of at figures has been set. The full keyboard follows the card diagram to be treated therefore in columns. As the keys are held fast until the next movement of the carriage, the operator always has before him the group in of figures set, and can control or check it separately, which is easier than if he had to check at once the whole number of figures.

A construction according to the invention at is illustrated by way of example in the accompanying drawings in which Figure 1 is 'a vertical section at right angles to the longitudinal direction of the machine.

Figure 1 is a detail View of the key looking means of the same.

Figure 2 shows on an enlarged scale a part of the punch box with the setting device.

Figure 3 is a vertical longitudinal section. F gure 4 is a partial plan of the machine. Figure 5 shows the feeding device.

The punch box with the rforators or punches and the matrix is o the construction usual in card punching machines.

Between two plates 1 and 2 (Figures 1 and 2) secured to the frame of the machine, are arranged the punches 3. Under the punches is arranged the hole plate or matrix 4 which can be raised by a pair of eccentrices 6 mounted on the spindle 5, by means of rollers 7. A perforation or punching of the card K placed on the matrix is then effected at those points at which the punches are locked in the low position shown in Figure 2 for the central punch. effected by means of pawls 8 which are adj ustahly mounted between the guide plates 16 and 17 also seeured to the frame of: the machine, and may be depressed by the keys and held last in the low position by locking slides 9. V

The setting carriage comprises an upper plate 10 and a lower late 11 which are connected together to orm. a fixed frame by means of lateral sheet metal plates 12 (Figure 3). This frame is easily adjustable in the lateral direction on rails 13 and 14 which are secured to the machine frame, and is pulled to the right by means of two' steel bands 15 (Figure 4:) by a spring mechanism not show in the drawing. The pawls 8 are set directly by means of the keys. As the keys must be arranged so as to ensure convenient striking, and as the arrangement of the pawls depends on the fixed arrangement of the holes in the card, the transmission parts between the keys and the pawls must be brought together in a correspondingly narrow space. This can be done either directly by using bent key levers or, as shown in the drawings, by pushing parts which may be in the form of Bowden wires (Figure 1). It will be seen that the Bowdcn wires are groupedin a conical or converging arrangement (see Figs. 1 and 8). In this case, to the upper plate 10 and to the lower plate 11 are carried closely wound spirals or helical springs 18 (Figure 1) inside each of which is arranged a thin wire 32 which constitutes the transmission element. To the wires 32 are connected the key stems 21 carrying the keys This locking in 20. A'pressure spring 37 arranged inside the socket for the spiral keeps the keys in. the normal position. When a key is depressed, the corresponding pawl 8 (Figure 2) is therefore depressed, the slide 9 snaps into the upper recess of the pawl and holds it fast, and the punch 3 is held in its lower position in opposition to the action of its spring. In the case of a keyboard with nine places, punches may be set accordingly 1n nine rows.

In order to enable the whole range of the punching box to be set with the keyboard, the latter, as already stated, is adJustable in the lateral direction. Under the action of pulling by the bands 15 operated by a tension spring, the whole keyboard has thetendency to move to the right, but is prevented from doing so by the finger 28 which engages in front ofonc of the stops 23 (Figui'eS1,"3 arid-5). "The stops are mounted in slots' 'in arackf24 secured to the frame of the machine7The-stops may be placed'at any desiredgpoints of the said rack. The releasebfth setting carriage is effected by a separate key 25 which acts on a lever 22.

- This lever rests on an arm 26 having a wide hub '27 with a tappet 28, which is so mounted on the spindle 29, that, under the action of a spring 30,-it moves to the right on the said spindle. Moreover the tappet is so connecte to the spindle by a groove and spline that the spindle participates in the rotation of the lever. To the spindle is also secured a second tappet 31. The two tappets 28 and '31 are so arranged at an angle to each other so that in the two end positions of the oscillation, one of them engages with one of the stops 23. The parts 25 to 31 and 38 are secured to the setting carriage. If the key 25 is depressed, the tappet 28 is turned by means of an intermediate lever 22 and the arm 26 so that it is released from the sto 23 in front of which it had been situate andmoved to the right by the action of the spring 30. At the same time. the tappet 31 has assumed the position which was previously occupied by the tappet 28, but as it is in front of the Ste 23- with' which the tappet 28 was previous yin engagement, the

carriage is free and is moved also to the right by the action of the pulling bands 15, until the tappet 31 is stopped by the next stop 23. If the key 25 is now released, the tappet 31 will be released from the stop-23, the carriage is moved a little further still to the right, until the tappet 28 which has by now returned to the position of rest, strikes the stop 23, and its spring 30 is compressed until the lever 26 strikes the stop pin 38. Inthat way the setting carriage reaches its new position. The spring. 30 forms at the same time an elastic buffer for absorbing anyv shocks produced by'the carriage. When the setting of the keys has been effected in this position, the key 25 is again depressed, the carriage moves to the next stop and so on. In that way it is therefore possible to set the whole punching box by means of the small keyboard.

In order to render possible a checking of the figures set, the keys depressed in one position of the carriage. may be locked in this position for the whole period of this :uljustment. This is done in the following manner:

The wires 32 (Figure 1) terminate in looking cones 35. These cones are hold fast by a locking bar 36, of which there is one for each row of keys, as soon as they are depresscd down to the neck. The key remains therefore in the depressed position, and the figures set may be read on the keys thus locked. The advance key 25 releases the locking bars, that is to say, makes them free for a new adjustment at each advance of the carriage.

What I claim is:-

1. In a punching machine for statistical cards, a punching device having a plurality of rows of punches, corresponding rows of punch locking devices, a movable settin carriage having a keyboard provided w1t1 several rows of keys and provided with corresponding rows of key operated devices adapted to set in operative position punch locking devices above a plurality of punch rows which form a zone or portion of the total number of punch rows, a card carrier movable relatively to the locked punches, tabulating means including a tabulating key for moving said setting carriage step by step from zone to zone of the rows of punches, and means cooperating with the inner ends of said key operateddevices to lock the keys in depressed position, said key lockin devices being releasable by depression 0 the tabulating key. 2.
